SPECIFICATION forming part of Letters Patent No. 492,126, dated February 21, 1893.

' To all whom iv' may concern.:

Be it known that I, CARL W. WEISS, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Ignitors for Gas-Engines; and I do hereby declare that the following is a full and exact description thereof, refings, and to the letters of referencemarked thereon, making a part of this specification.

My invention relates to incandescentignitors for gas-engines and has for its object 'to provide improved means for holding the ignitor tubes whereby a broken tube may be replaced by a new one readily and quickly land whereby when one ignitor is disabled it if may be immediately cnt oi from connection .with the cylinder and the explosions may conthereby avoiding the stopping of the engine to put in a new tube: A further object is to prevent as far as possible the conduction of heat from the incandescent tube.

In the accompanying drawings, wherein I have illustrated my invention, Figure l is a side elevation of a portion of a gas-engine with two ignitors in position. Fig. 2 is a top View of one of the improved ignitors showing also a portion of the valve cylinder, and Fig'. 3 is a vertical central section on the line x-x of Fig. 2.

The cylinder A may be of any usual or preferred form or construction. It is formed with a hole a and a seat a for the reception of an independent tube B which may be secured to g; the cylinder by any convenient means, as a screw b, with an intervening packing b of i non-conducting material and has an inner end b2 of less diameter than the hole d. The outer end of the tube B is formed with a seat b3 for one end of the incandescent tube O and is fitted with a valve b4 to close when necessary the bore b5 of the tube B. As usual, the incandescent tube is surrounded by a jacket D, but I have improved the construction of the jacket to enable a broken tube to be'more easily removed and replaced. To this end the j acketis divided longitudinally into two parts d and d'l. The part OZ may be supported by any convenient means but I prefer to form it with a sleeve d2 to t upon a stud E fixed to the cylinder. The outer end of the stud is erence being had to the accompanying drawtinue to be produced by a second ignitoig' Application filed November 27, 1891. Serial No. 413,206. (No model.)

screw-threaded to receive a nut e to hold the jacket in place and to permit removal and ads The outer part, cl, of the jacket may be se-` cured to the fixedpart d by any suitable means which will prevent its ready removal, as by perforated lugs and pins as shown atd.

A Bunsen burner F is placed, as usual, in

a position to maintain the tube O in a condition of incandescence.

The tube B, which supports the incandescent tube O and conducts the ignited gas to the cylinder A is made independent of the cylinder and is insulated therefrom in order to prevent as far as possible the conduction of heat from the ignition tube and the consequent reduction of its temperature. The valve h4 may be operated from the outside to close the passage wayb5 between the ignition tube and the cylinder, and thereby to prevent the escape of'gas and the stopping of the engine whenever a tube breaks. As shown in Fig. l I prefer to fit two independent ignitors to the cylinder and to keep both in operation at the same time whereby the possibility of a failure to ignite the gas is very much diminished and whereby, if one tube breaks, its valve may be closed immediately andthe other may continue in operation without checking the operation of the engine.

Whenever any incandescent breaks the jacket may be opened, the broken pieces removed and a new tube put in place by adjusting the screw seat d', with great readiness and without necessitating the handling of any of the hot parts.

I claim as my invention-d l. In an incandescent ignitor for gas-engines, the combination with the cylinder and the incandescenttube, of an independent tube communicating with said cylinder and having a lateral seat for the incandescent tube, a jacket surrounding said incandescent tube and a valve-rod screw-threaded into the outer end of said independent tube and adapted toA ICO close its bore between its inner end and the seat for the incandescent tube whereby the latter may be removed and replaced without permitting the escape of gas from the cylinder, substantially as shown and described.

2. In an incandescent ignitor for gas-en gines, the combination with the cylinder, the incandescent tube and a seat for one end of said tube, of a longitudinally divided jacket to surround said tube, one part of said jacket being fixed and having a seat for the other end of the tube and the other part of said jacket being removable, substantially as shown and described.

3. In an incandescent ignitor for gas-engines, the combination with the cylindei` and the incandescent tube, of a fixed arm having its end in line with said tube, and a chambered screw carried by said arm and forming a seat for the outer end of said tube, substantially as shown and described.

In testimony whereof I have signed my name `to this specification in the presence o1 two subscribing witnesses.

CARL WV. WEISS.
